ELASTIC ROCKER ATTACH M ENT SPECIFICATION forming part of Letters Patent No. 653,351, dated July 10, 1900. Application filed February 9, 1900. Serial No. 4,624. (No model.)

To aZZ whom it may concern.-

Be it known that we,THoMAs F,KNIPIIUISEN and WILLIAM P. KNIPHUISEN, citizens of the United States, residing at Clymer, in the county of Ohautau qua and State of New York, have invented certain new and useful Improvements in Elastic Rocker Attachments; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in attachments to rockingchairs, cradles, &c., and especially to the 'provision of an elastic or rubber strip which is adapted to be held to the under face of the rocker, whereby the chair or cradle will rock smoothly and quietly without slipping or sliding while the chair or cradle is rocking, and in carrying out our invention it is our purpose to attach the rubber strip in anysuitable manner, as upon the flat surface of the rocker or in a groove, whereby the strip may be held more securely in place and held to the rocker by means of suitable fastening devices.

To these ends and to such others as the in vention may pertain the same consists, further, in the novel construction, combination, and arrangement of parts, as will be hereinafter more fully described and then specifically defined in the appended claim.

Figure 1 is a perspective View of a portion of a rocking-chair, showing our improved elastic cushion therefor. Fig. 2 is a cross-sectional view through the rocker and cushion.

Reference now being had to the details of thedrawings byletter,A designates therocker, which may have a fiat or convexed under surface and provided with a central longitudinal groove B, which is preferably semicircular in outline and adapted to receive the I elastic cushion-strip O; "This strip'extends, preferably, the length of the rocker and at different locations is slitted in from one side, as at D, in which slits are inserted the disks E, which are centrally apertured, and at intervals'along the length of the rocker and the elastic strip pins F are driven through the elastic strip, through the central apertures in the disks, and the shank portions of said pins are driven into the wooden rocker, whereby the said strips are securely held in place. In the drawings we have shown the elastic strip as having diametrically oppositely disposed ribs H, through which. fastening-pins G are passed, which are driven into the rocker, as shown.

By the use of the cushion-strips secured to rockers in the manner described the slight vibrations are taken up, the rocker is prevented from slipping, and no noise is caused from the rocking of the chair or cradle.

Having thus described our invention, what we claim to be new, and desire to secure by Letters Patent, is

In combination with a rocker having a grooved bottom, an elastic cushion having wings which are secured to the rocker, said the upper faces of the wings, apertured disks seated one in each of said slits, the aperture of each disk when thus seated, being in registration with an aperture through the cushionat right angles to the slit, and a nail passed through said aperture and washer, and driven into the rocker, the head of the nail being seated against the lower face of the washer, as shown and described.

In testimony whereof we affix our signatures in presence of two Witnesses.
